A father and son duo allegedly duped a number of five-star hotels in the city by eating at restaurants and then making a run for it without settling the bill. They used to pretend to be tired guests who dined without checking in. Then, eat to their heart's content at fine dining restaurants and slip away without paying.

Their jig was up on Saturday when the staff at Vivanta President, which is a Taj Group hotel, caught them and informed the police.
